SOCKET REVERSIBLE RATCI-IET-WRENCH.

Specification of Letters Patent.

Patented Dec. 21, 1909.

Application filed April 12, 1909. Serial No. 489,545.

To all whom it may concern.-

Be it known that I, DAVID F. VoLnMnn, a citizen of the United Qtates,residing at Monroe. in the parish of ()uachita and State of Louisiana,have invented certain new and useful Improvements in Socket ReversibleRatchet-\Vrenches, of which the following is a specification.

My invention has relation to socket reversible ratchet wrenches and itis made specially to be used at fish plate joints of railroads. Thesockets are made in ditferent sizes and can be interchanged at will.

The main object of my invention is to produce a wrench of the type abovementioned, which is provided with such clamping means that it will holdthe head of the bolt in proper position while the nut is be: ing screwedon the other end thereof.

Another object of my invention is to produce a wrench of this characterwhich is simple of construction, efficient in use, durable, and whichmay be manufactured at a reasonable cost.

With these and other objects in view, my invention consists of the novelconstruction and arrangement of parts as are hereinafter described inthis specification, illust 'ated in the accompanying drawings forming apart thereof, and particularly pointed out in the appended claims.

Referring to the drawings: Figure 1 is an edge view of my invention,shown as it is applied. Fig. 2 is an edge view of my invention, partlyin section. Fig. dis a side View of my device, shown in section, withthe exception of the handle. Figs. 4: and 5 are details.

-Referring to the drawings more specifically, my invention is describedas follows: The handle 1, is so bifurcated at its lower end that itforms the two extensions 2 and 3, each of which is circular in shape.Passing through each of said extensions is an annular hole el, each ofsaid holes being of the same diameter and one arranged opposite theother.

A ratchet wheel 5, provided with a square hole at its center, has formedone on each side thereof annular necks 6 and 7. Said necks are adaptedto be engaged by the holes in said extensions 2 and 3, and it isintended that they should rotate in said holes as bearings. Said neck 6,projects such a distance that its surface is even with the surface ofsaid extension 2. Said neck 7, extends such a distance beyond thesurface of said extension 3, that a collar 8, provided with a hole thediameter of which is equivalent to the diameter of said neck. may bemounted loosely thereupon. Said ratchet. wheel 5, is provided with anumber of teeth 9, said teeth adapted to be engaged by either of thedogs 10 or 11, either or both of which may be thrown out of engagementat will. Said dogs are pivotally mounted in a suitable manner betweensaid extensions 2 and 3. That these dogs may be thrown out ofengagement, I provide a spring extension 12, one of which is secured toeach edge of said handle 1, immediately above the bifurcated portionthereof. Each of said spring extensions is provided with a. raisedportion 12, leaving a concave surface on their under sides wherein lodgesaid dogs when they are thrown out of engagement.

A socket 123, is provided with a shoulder 14-, from which joint saidsocket tapers down to the diameter of the core '15. This taperingportion will be hereinafter designated as the rotary head and will benumbered 16. The core 15, passes through said hole at the center of saidratchet wheel 5, and adapted to be rotated thereby. A square. hexagonalor octagonal or other shaped hole 17, passes through said core 15, fromend to end. This hole is for the purpose of receiving the nut that is tobe screwed upon a bolt, the head of which is held in place by means of aclamp 18. Said clamp 18, has one portion extending horizontally, anotherof its portions extends vertically, the lower end of which is inwardlyturned. The inner end of said horizontal portion is pivotally connectedto an car 19, formed or secured at the periphery of said collar 8. Themanner of engaging the head of a bolt, while the nut is being tightenedthereon, is illustrated in Fig. 1. The said'core 15, is held against thesidewise movement by means of a pin 20, passing through said ratchetwheel and one of the corner edges of said core. The rear face of saidrotary head 16, abuts against the end face of said annular neck 7.

Although I have specifically described my invention, bringing forth itspreferred construction, yet I may exercise the right to make such slightdeviations in its general form and arrangement as do not depart from thespirit thereof, and as fall within the scope of the appended claims.

Having described my invention, what I claim is:

1. In a wrench of the class described comprising a bifurcated handle, arevoluble element mounted for rotation between the extensions of thebifurcated portion, said element provided with a neck formed on eachface thereof, which necks are received by holes in the extensions, oneof the necks extending beyond the surface of that extension throu 'hwhich it asses, a collar loosely mounted on the last-mentioned neck, asocket extending through the center of said element and rotated thereby,the collar being held on said lastementioued neck by the socket, a clampconnected to the collar at the periphery thereof, said clamp assistingin holding the head of a bolt in place while said socket is turning anut upon its other end.

In a ratchet wrench of the class described comprising a bifurcatedhandle, a 'atchet wheel rotating between the extensions of saidbifurcated portion, said wheel provided with a neck formed on each sidethereof, which necks are received by suitable holes in said extensions,one of said necks extending beyond the surface of the l extensionthrough which it passes, a collar l loosely mounted on saidlast-mentioned neck,

a socket passed through the center of said wheel, rotated thereby, andholding said collar in place, a right-angular clamp pivoted to saidcollar at its periphery, said clamp holding the head of a bolt in placewhile said socket is turning a nut upon the other end thereof,substantially as shown.

3. In a ratchet wrench of the class described comprising a bifurcatedhandle, a ratchet wheel rotating between the extensions of saidbifurcated portion, said wheel provided with a neck formed on each sidethereof which are received by suitable holes in said extensions, one ofsaid necks extending beyond the surface of the extension through whichit passes, a collar loosely mounted on said last-mentioned neck, asocket passed through the center of said wheel, rotated thereby, andholding said collar in place, a right-angular clamp pivoted to saidcollar at its periphery, said clamp holding the head of a bolt in placewhile said socket is turning a nut upon the other end thereof, saidclamp having a horizontal portion and a vertical portion, the lower endof said vertical portion being inardly turned, the inner end of thehorizontal portion being the point at which said clamp is pivoted tosaid collar, substantially as shown.

In testimony whereof I atlix my signature, in presence of two witnesses.

DAVID F. VOLLMER.
